First time builder of PC... won't turn on

I just got all my parts and put all the pieces together and the computer will not turn on. This is the first time i have built a computer from scratch, however I have replaced parts from my old computer so I have pretty much placed all parts onto a computer. I have found one problem that my power supply won't support the graphics card I have due to the fact it needs 2 6 pin power inputs for it... however I dont think that would be a reason for the entire system not to turn on. Here is the list of my parts:

The Power Supply and the Disc Drive I am using for my new computer are the only things I am scrapping from my old computer so I know it works. I tested to see if it was the switch broken by connecting the 2 Power pins with a conductor (Switch is broken on this computer and I have to do that to power it on). Is there any compatibility issues with these products? All of them fit perfectly into place so I am really unsure what exactly the problem is. After my new PC didn't work I unplugged everything pulled out the power supply and rewired my new PC and it turned on fine. So that lets me know that I am wiring things properly and the PSU is working. Any suggestions?

I am not sure on the exact model (I'm at work but can edit this later), but I know the brand name is Dynex and I remember it not being too expensive either (I would guess 50-80 bucks 2 years ago) compared to the power supplies that normally run a system like this. I know I am going to have to upgrade the PSU anyway for the graphics card so I will try this all with a new PSU. Yea the CPU connection is in, but in the manual for the Motherboard it says atleast 300W in order to run it so I assumed I would get some spark of life when i turned it on, no fans spinning.. no lights, no signs of life at all. Can the PSU being too weak cause all of this? And if so, how much Power do you think would be safe to go with in order for this to work?

I should think you would be getting at least the fans turning, but it won't POST with no power to the graphics and I wouldn't advise running it at all until you can get a decent PSU. I'd be looking at something like the Corsair VX-550 as a minimum.

When you get a much better quality PSU, then follow these instructions:
